A sample of 30 of 178 funded projects revealed that 12 were valued at $17,360 each and 18 were valued at $20,280 each. From the sample data, estimate the total value of the funding for all the projects. (Enter your answers to two decimal places.)
$ 35.60 was my answer

this is how I worked it 12+18=30, 12/30=.4, .4X178=71.2
12+18=30, 18/30=.6, .6X178=106.8
I first got 178.00 then I redone and got 35.60
